With its 13.5 hp diesel engine, which is powerful and economical and the equivalent of a 20 hp petrol engine, the GR1600-II offers more power and greater fuel economy when compared to petrol mowers. Unlike the belt-driven system that can be found on most ride-on petrol mowers for the general public, the GR1600-II has a wet-type mechanical PTO clutch and shaft-drive transmission. This built-in robustness guarantees extended service life and significant residual sell-on value.
